When Martin almost gets a parking ticket, Tim thinks it might be a good idea if Martin legitimizes his Earthly driving by getting a driver's license. Down at the Department of Motor Vehicles, finger-printless Martin has to do some fancy work when he is about to be finger printed. He steals the prints of another man at the DMV. Unfortunately for Martin, that print matches the only unidentified print at a major jewel robbery the previous year. In a routine cross check, the police find the print in Martin's file. And Tim covered the jewel robbery for the paper, something the police find probably more than just a coincidence. Martin and Tim find out that the police are watching them and the reason, and so Martin thinks it a good idea to flush out the jewel thief: he reads that there is a party where Mrs. Summer Winthrop will be displaying the galaxy diamond necklace around her neck, a lure too irresistible for the thief. At the party, the guests are populated predominantly by police - both in uniform and under cover - and the thief, Brian Henley, and his female accomplice, who Martin recognizes from the DMV office. Henley manages to slip the necklace off Mrs. Winthrop, slip it to his accomplice, who in turn slips it into the crown of the cap of Captain Farrow, the lead police investigator. Henley plans to steal the necklace back after the place has been unsecured, and he is no longer a suspect (he was the only person close the Mrs. Winthrop when the necklace went missing). Martin, seeing where the necklace was stashed, plans to plant it back on Henley. No matter what Henley does to get rid of the necklace Martin plants in his pocket, he is no match for Martin's levitation finger. Henley is quickly apprehended, and Martin and Tim cleared.
